Is that even possible?

It could be but chances are extremely low.
To be very honest, there is no method or technique in the world which will get you 100% guaranteed win.
As we are talking about sports betting, which is another way of spending your money on somebody else's luck.
So, I am sure this is just another spam post to attract attention and nothing else.
I will advice everyone to stay away from such beliefs and sayings.
There's a good chance that it is.
But it integrates me he wrote such a topic explaining it i'm not going to take his/her beliefs regarding what he's saying.
I guess staying away is the best thing someone can do.
